CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 460,936, dated October6, 1891.

Application filed October 28, 1890. Serial No. 369,635.

To all whom it may concern.-

Be it known that We, WILsoN LUMPKIN Goss and WILLIAM HARMAN HARRELL,citizens of the United States, residing at Dallas, in the county ofDallas, State of Texas, have invented anAutomatic Car-Coupling,of whichthe following is a specification.

Our invention relates to an improvement in car-couplings for all kind ofrailroad-cars; and the objects of our improvement are, first, to providean automatic car-coupling that is simple in construction, strong anddurable, easily adjusted and repaired, and effectual in its action;second, to provide a coupling that can be operated when coupling carswithout the operator going between the cars. \V e attain these objectsby the mechanism illustrated in the drawings accompanying thisspecification, in which Figure 1 represents a top view of the couplingcomplete. Fig. 2 represents a vertical sectional view of two couplingsas they come together in coupling cars, the left sect-ion being lockedand the right section set ready to lock. Fig. 3 represents a top view ofhook A and ratchet- B. Fig. 4 represents a section of box-car withcoupling attached and lever for unlocking coupling. Fig. 5 represents averiical section of coupling, and represents more fully the operation ofthe coupling. Fig. 6 represents a front or face view of coupling withhook A broken off. Fig. 7 represents a top view of the coupling withhook A broken off. Fig. 8 represents shaft or pin D and key 0substantially.

Sim ilar letters refer to si milarparts thro ughout the several views.

The coupling consists of cast-iron heads J J, securely bolted togetherwith bolts G G, which is fully set forth in Figs. 1 and 7. Hook A andratchet B are cast or forged solid from cast-steel, and hook A andratchet B- have eyes through them just alike with key-slot, and lit overcollar R, which is made with keyflange on outside, all of which is fullyset forth in Fig. 5. Hook A and wheel 1- are placed on collar R, and arethen placed in posi tion in head, and pin D is putin position, passingthrough collar R,and is secured in place with key 0. Pin D and key 0 aremade from steel, and are fully set forth in Fig. 8. Coil- (No model.)

spring E and spring H are made of steelspring wire, and aresubstantially set forth in Fig. 5. Spring E is looped around bolt G, andis made fast to hook A through eye I). (See Fig. 5) Ratchet-dog F ismade, as shown in Fig. 5, from steel, and is secured in position by boltI, and is reamed or hollowed out on one side, and spring II is placed inthe hollowed side of dog F, and is held in place by end of springpassing through bolt I, as shown in Fig. 5.

Then the parts are all in position, by raising hook A, as in Fig. 5,ratchet-wheel B is turned so that dog F is thrown into notch on wheel Bby spring H, and thus held. The lower end of dog F is thrown to thefront, so that when the heads come together in coupling cars dog F ispushed back and hook A is pulled down by spring E, and hook A catchesover pin D in the other coupling, (see Fig. 9, left view,) thus couplingthe cars together, and when coupled there are two hooks in everyconnection, thus giving all the strength required, and the shape ofratchetwheel B is such that when the coupling is locked the lower end ofdog F is drawn back into the head and secured from harm by heads bumpingtogether when cars are in motion; and when desired to uncouple cars hookA is raised by a simple lever device, as shown in Fig. &, or by shortcrank part on end of pin D.

The advantages we claim for our coupling are as follows: It is simpleand durable, every part is made separate, and should any part be brokenit can be replaced in a moment with duplicate-to wit, by taking out pinD, hoo'k A,ratchet-wheel l3, and collar R, all separated-and each can bereplaced with duplicate in a moments ti me, and by taking out bolt I dogF and spring H can either or both be replaced at will secondly, the coupling will work just as well where adjacent cars are of differentheights, the hook from one hooking down and the other hooking up, sothat the strength is preserved; third, the operator need never gobetween the cars to couple them.

\Ve are awareof the fact that there are many patents already granted oncar-couplings, and we do not claim any patent on the shape or form ofthe heads, as represented,

nor the manner in which they are bolted toet-dog F, spring H, and key 0,substantially V gether or attached to the cars, as the lever asdescribed.
